The Lowdown
Alright, let’s take a look at what’s happening on our local stretch. I gotta be honest, the next couple of weeks start off real slow. The ocean’s pretty much flat for days, just taking a snooze. But there’s a couple of pulses coming through later that’ll get the blood pumping.
For Kennebunk Beach, we’re in for a dry spell. From Saturday, August 29th, all the way through to Tuesday, September 1st, the surf is tiny and sad. We’re talking ankle-to-knee-high junk with weak energy (down to just 11). Wind’s all wrong, too – mostly onshore or cross, making it a total washout. The morning of the 1st has a little offshore breeze, but the waves are only 0.4m, so it’s just a clean little glass-off with no real power.
Roll into Wednesday, September 2nd, and we get a small bump. The morning has a 0.6m swell from the SE, and the period jumps to 11 seconds – that’s proper groundswell starting to show, even if the energy is still only 75. The wind is light and cross-shore, so it’ll be a bit bumpy but rideable on a log. The afternoon gets chopped up by a stronger cross-onshore wind, so the morning is the only window.
Now, here’s the standout. Thursday, September 3rd afternoon is the moment we’ve been waiting for. The morning is bumpy with a 2.2m swell from the SE and cross-onshore wind. Not great. But by the afternoon, the wind swings to a light cross-offshore breeze from the NNW, cleaning everything right up. We get a solid 2.1m swell from the SE, and the energy jumps to a beefy 452 – that’s a proper push of power. The period is short at 7 seconds, so it’ll be a bit fat and lumpy, but with those clean conditions and that size, you’re looking at punchy, hollow-ish waves. For experienced surfers only, though – that’s big enough to be real grunty. Not a day for beginners.
After that, the swell backs off. Friday, September 4th and Saturday, September 5th have clean-ish windows, but the waves drop to 1.4m and then 0.8m. Energy is moderate at 217 and 125, and the wind is mostly cross or cross-off, keeping the bumps down. Surfable, but nothing special.
Then we hit another lull from Sunday, September 6th, through Monday, September 7th – the waves pretty much vanish.
But hold onto your board, because Tuesday, September 8th morning gives us another solid chance. The morning is clean with a light cross-offshore breeze and a 1.9m swell from the ESE, with energy at 406 – another strong pulse. The period is still short at 8 seconds, so it’ll be punchy and a little walled up. It’s a solid second choice, but the wind goes onshore by the afternoon, so get out there early.
After that, it’s back to small, choppy, and poor for the rest of the outlook. The water temperature is about what you’d expect for this time of year. So, bottom line: the clear winner is Thursday, September 3rd afternoon at Kennebunk Beach. Clean, solid size, and a good amount of grunt. Tuesday, September 8th morning is your backup. The rest, you might as well wax up your board for next week.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
